The Japanese automaker said on Friday that a software and parts problem can cause hydraulic pressure to build in the braking system after an engine restart. The buildup can suddenly be released, causing heavy and unexpected braking without the brake lamps coming on.

Honda said it is not aware of any crashes or injuries related to the problem. Honda says it will replace a "yaw sensor" but the part won't be available until early next year.

In the meantime, it issued instructions on line on how to drive to prevent the problem from occurring.
